in species, whicli do nol lielong lo Ihis f^roup, nnd patlly because llie are not 

 found in all ils species. The most characteristic structure is of course that 

 found in tlie sexual organs and the coxal sac of tlie male; others, less im- 

 portant, but more practical, because they are apparently only found in species 

 of this group and probably in both sexes, may be taken from the broad 

 second transverse stripe and from the shape of tlie terminal lateral hair of the 

 tarsus. Only 20 of those described about 175 species of Chelifer Geof. can with 

 security be referred to this group; and these can perhaps be divided into two 

 maniples, of which the first only includes Ch. scalptiiratus Lew., remarkable by its 

 big granulations, toothless claws, shape of the coxa IV of the female e.t.c. (cf. p. 123; 

 21. pp. 117—123). Ch. Mortensenii n. sp. and Ch. gramilniiis C. K. are representanis 

 of groups of minor value. 



2. The Ch. snbruber Sim. group is characterized by the following structures. 

 Real eyes or ocular spots present. Two transverse stripes and skin granular with 

 clavate hairs. Genital area of very simple structure and with the posterior plate 

 longer than the anterior (cf. p. 121; pi. Ill, fig. 7b); the sternites of the male is beset 

 with a large number of short spines (cf. p. 129; pi. Ill, fig. 8 b). The articulation 

 between the trochantin and the femur proper of the first pair of legs very narrow and 

 differing from that of all other forms (cf. p. 37; figs. 5 a-b). The tarsal '-tactile" hair 

 is median. Only two species, Ch. subruber Sim. and Ch. Murrayi Poc, which differs 

 from each other in many respects, can be referred to this group, which may per- 

 haps be regarded as the central one in the whole subfamily for the simple structure 

 of the genital area and the slightly developed articulation of the first pair of tro- 

 chanlins. I think, that a great many of the species with real eyes, which do not 

 belong lo "Lophochernes Sim.", may possibly be referred to this group, even if such 

 a character as the armature of the sternites fails. 



3. The Ch. Hirnianicus Thor, group is characterized in the following way. 

 No eyes, but ocular spots often present. Céphalothorax smooth with pointed hairs 

 and without tranverse stripes or with indistinct ones. The genital plates (c?) 

 of almost equal breadth and length, but the posterior with two in the middle 

 backwards curved sclerites (cf. p. 124 and pi. Ill, fig. 10 a). The articulation of the 

 femur of the first pair of legs wide and of the usual structure (cf. p. 37), and 

 their tarsi always much shorter than the tibia. The tarsal "tactile" hair is basal. 

 This group seems lo be well characterized by the genital area of the male as well 

 as by the basal position of the tarsal „tactile" hair, and includes jirobably by far 

 the greatest numljer of species described, embracing all referred lo Atemnns Can. 

 and many of those belonging to Lamprochernes Tom. Most species belonging lo 

 this group appear rather uniform and do not provide many striking specific modi- 

 fications, Ch. equester With partly excepted (21. pp. 123 — 127). 



4. The Ch. cimicoides F. group is characterized so. No ej^es but sometimes 

 ocular spots. Distinct transverse stripes. The fingers of the palps with accessory 

 teeth. The anterior genital plate longer than the posterior and of |)eculiar structure
